IMPROVBIVIENT IN' FLUID-METERS.

'he Schedule referred to in these Letters Patent and makiiig part cf the .am'

To all whom 'it may concern:

Be it known that l, CHARLES Moons, of the city and State of New York, have invented aml made certain new and useful Improvements in Fluid-Meters; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawhlg, making part of this` specitication, wherein- Figure 1 is an elevation of said meter, with the capplate. ot'the motor broken open to show the cranks;

Figure 2 is a section vertically of theA motor at the line z z ot' lig. 3;

Figure 3 is a sectional plan at the line y y, fig. l

Figure 4 is a sectional plan ot' the valve of the m'otor at the line x x;

Figure 5 is a vertical section of the indicating-mechanism; and Y Figure (i is a plan of part of the friction-wheel and clamp for moving the imlicator.

Similar marks` ot' reference denote the same parts.

This invention .is intended to measure the quantity of water, or other liquid, gus, or other iuid, that may be allowed to pass through a pipe. lhe registeringmotion is derived from the lluid that passes through a small pipe, and acts upon swinging pistons or diapluag:ns,iaiul the extent of register-iiig-motion is increasedproportionately to thc movement given to a swinging gate in the main supply-pipe,'sothat when but a small quantity ot' liquid is beingused, the measure will be accurate, aml when there is a large amount of iuid passing through thc pipe, the measure is et'- fected by the increased movement given to the registering-device by the motor-portion ot' the apparatus, in consequence ofthe gate being opeued'by the liquid iiowiug past it. This renders it unnecessary to have all the iiuid pass through the motor-portion of the appara-tus; hence this meter can be. adapted to large or to small pipes with facility, and without change in the motor-portion. 4

In the drawingka represents a square trunk or pipe', to the ends of which the water or Huid-pipes lare connected; \Vitliin this a gate, b, is hung, as shown by dotted lines, tio". 1, and this acts at its fulcrum upon the pinion c and segmental pinion and arm d, for a purpose hereafter named.

lVhen only a small quantity of liquid is being drawn, it passes in at the oritice c, (see tig. 3,) through the motor, and returns on the other side of b into the tube a, by the openhlgf- When the quantity ofliuid exceeds the capacity of e j, then the pressure causes the gate b to 'rise a distance proportioned to the quantity of liquid or iiuid passing along through a., aml this motion makes the registeringmechanism denote the propel' measure of the tluid.

lhe orifice e is connected with the inlet-ports of the respective chambers h ,'as hereafter described.

The pistons, or diaplnagms k l are fitted to swing in the chambers h i, upon them-hors or shafts 2 and 3.

.valve p. The length of these respective cranks is such that the swinging of the pistons It' l in their respective chambers shall cause the rotation of the Valve p.A

This rotary valve p is made as a cylinder from which segments are removed on opposite sides, as seen in tlv. 4, to form water-ways, one opening at 'the ti'ont into the chamber n, and the other at the rear into theschannel q that connects with the outlet f. 9 and l0 are the ports to the chamber t', and there arc corresponding ports, 11 and 12, to the chamber It, shown by dotted lilies in tig. 2, also in {ige/,1. g

The water passes through the hole I3 lntothe chamber n., and by the rotation of the valve p, said water or tluid is admitted, to first one side of the piston l, and then the, other, the eduction on one side heilig opened sinnlltanebusly with the induction ou the other side of thc pistou l. Y

The tluid is admitted'to act upon thepiston k in the same manner, but in consequence ofthe arrangement ofthe cranks 4 and 5, and connections, there is a. suttcient lead for one piston to complete its stroke, while fr see ti r. 4 l at the rear end of the arbor of the rotary valve 1), which crank fr acts in the slot of a swinging lever, s, that is jointed at its upper end to the t'eedv motion arm t, and has for its fulcrum a pin, u, in the' end ofthe arm (l.

The registeriiig-apparatus is formed of a wheel, n', acted upon by clamping-pawls 15, that are similar in action to the clamp. of a wheel-feed on a sewing-machine. v

These clamps 15 are upon aplatc, 16, that has the stud 17 for its centre, and it will now be apparent that when the gate bis closed, the clamps 15 will move the wheel n a given distance each rotation of the valve p, but when the gate b is raised, the fulcrum yu is lowered, increasing the motion of the clamps and the wieel la in proportion to the amount the gate b is. raised, and the consequent tlow ofthe tiuid.

From the wheel 4u the indicator or dials usually employed to register the number of revolutions receive motion. I have shown a series of wheels for this purpose.

Upon the wheel u' is a pinion, 20, the teeth of which gear into the teeth around a stationary circular rack, o, and also into the teeth on the under side ofthe wheel w. There is one less tooth in the wheel w than iu the rack u hence, for every revolution ot' the wheel u, the wheel u' will be moved the extent ot one tooth. This mode of indicating the numbervof revolutions may be still further extended by using the pinion 21, rack 1v', and wheel fc.

The arbors ot" the respective wheels w and a: are to be pipe-shaped, and provided with hands or dials, and if required, the computation might be. still further extended hy the use ot'a greater number of wheels and racks.

That I claim, and desire to secure by Letters Pat,- ent, is-

1. The combination of the-following devices: tirst, the swinging pistons k I, actuated by a portion of' the Huid; second, the gate b, that. is opened in proportion to the tiow ot' water; third, the indicator that is conneoted to the gate, substantially as set; forth, so that the movement of' the gate causes the indicator to act in proportion to the iiow of water, as specified.

2. The swinging,r pistons k l in the ohmnbers h i, iu combination with the rotary valve p, inlet and eductiou-ports 9, 10, 1l, 12, and cranks 4, 5, and 8, arranged and acting in the manner and for the purposes set t'orth.

3. The lever-link s, between the crank rand clamp that operates the wheel u of' the indicator, in combination with the arm l and fulcrum-pin u, operated by the movement of the gate b, as and for the purposes set forth.

4. The indicator, formed of` the `wheel u', pinion 20 rack e, and wheel w, in combination with the actuating clump 1G and levers moving the same, as set; t'orth.

lu witness whereof", I have hereunto setmy signature. this 9th day ot March, A. D. 1869.
